Draw the products of the complete hydrolysis of the mixed acetal shown. Draw all products of the reaction, including the alcohols produced. Although the picture shows all of the attached hydrogens, you don?t need to draw in hydrogens apart from hydroxyl hydrogens.

For a catalyzed reaction: a) Does the catalyst change the energy of the reactants? Of the products? If so, how? b) Does the catalyst change the energy of the transition state? If so, how? c) On the graph below, draw the following: • An exothermic reaction indicate by drawing a solid line) • The same exothermic reaction, but with the...

11. (2 pts) Formation of the enamine is facilitated by making use of the Le Chatelier principle. One of the products of the reaction is physically separated from the other product by removal from the reaction mixture, which prevents the reverse reaction. Which is the product that is physically separated? 12. (2 pts) Which technique is used to physically separate...
